GLOBE CLOCK Filed Feb. 18, 1939 2 Sheets-Sheet 2 ATTORNEY Patented Dec. 3, 1940 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to terrestrial globe clocks in which a globe containing a map of the world has associated with it clock mechanism for indicating the time in various parts of the world.

An object is to produce a new and improved terrestrial globe clock of the above'character in which the time indicator is arranged inside of the globe but when the inside of the globe is illuminated the time indicator is visible from the outside, so that the globe is unobstructed and can be readily examined but in which the clock feature may be visible as desired and will readily display the corresponding time in different parts of the world.

Another object is to produce a globe clock of the above character wherein the clock mechanism is disposed within the globe and which is mounted together with the time indicating device in a simple and efllcient manner.

Another object is to produce a globe clock of the above character with the time indicating device inside of the globe and with the globe so mounted that it can be turned for examination of different parts thereof without affecting the clock mechanism so'that the relative arrangement of the globe and time indicating device will not be altered.

Other objects and advantages will hereinafter appear and for purposes of illustration but not of 3 limitation, an embodiment of the invention is shown on the accompanying drawings in which Figure 1 is a side elevation of a terrestrial globe clock with a portion thereof broken away to show a time indicating device disposed on the inside 35 of the globe;

Figure 2 is a view partly in cross section, the section being taken on a vertical plane which approximately bisects the globe shown in Figure 1;

Figure 3 is an enlarged view of the clock driving mechanism and associated parts, partly in cross-section, the section being taken on approximately the same plane as the view shown in Figure 2;

Figure 4 is a transverse sectional view with 45 some of the parts removed showing the gear drive for the time indicating device; and the section being taken approximately along the line 4-4 in Figure 3 and looking in the direction of the arrows;

Figure 5 is a transverse sectional view substantially on the line 5-5 of Figure 3.

The illustrated embodiment of the invention comprises a globe clock consisting of a glass sphere it made up of two parts fitting together in overlapping relationship. Suitably mounted on the outside of the globe is a map of the world II which may be of paper or may be painted thereon or otherwise suitably displayed in such manner that a lamp on the inside of the globe will illuminate the outside thereof. As will hereinafter appear, the globe III is mounted on a base l2 to which leads wires l3 having a connecting plug l4 at the outer end. Switches l5 and ii on the base i2 control the clock operating motor and the lamp respectively as will hereinafter appear.

The lower section of the globe I0 is formed with a rectangular opening I! which fits over a similarly shaped projection IS on an annular block IS. The block I9 is rotatable in a recess 20 formed in the upper part of the base l2. It will be observed that the inside of the base I2 is hollow and extending through the upper wall thereof for turning movements therein is a tube 2|, the upper end of which is screw-threaded into a platform member 22. The tube is provided with a polygonal flange 23 which abuts against the underside of the upper wall of the base and depending therefrom is an extension 24 carrying the three vertically spaced contact rings 25 with which brushes 28 carried by spring arms 21 engage. The spring arms are suitably connected to the switches l5 and ii in the manner indicated in Figure 2. The wires from the contact rings 25 extend upwardly through the extension 24 and tube 2| and thence through a tube 28 from which wires 29 are connected for operating an electric motor 30 and other connections lead to a base 3| of any suitable type on which an electric lamp 32 is mounted. Mounted on the upper end of the tube 28 is a. wire bracket 33 which extends on both sides of the lamp 32 and provides a support for a connecting device 34 which holds the two sections of the globe Ill against separation. The bracket 33 is provided at its upper extremity with a screw threaded projection which extends through an opening in the upper section of the globe ill. The connecting device 34 threadedly engages this projection and functions to retain the upper section of the globe in proper position. The connecting device 34 extends through an opening in the upper section of the globe in such manner that the bracket 33 can turn when the globe is turned or rotated upon its base l2.

The platform member 22 has a relatively wide platform part 35, a reduced connecting part 36 which embraces the tube 2| and a lower part 31 which cooperates with the block I! in clamping the globe in position, a suitable gasket 33 being interposed between the part 31 and globe. A set screw ll extends through the reduced part I! and bears against the tube Ii for securing the parts against relative movement.

The platform part ll is formed with an annular recess ll in which nts a ring II for turning movement thereon. Secured to the upper face of the ring 4| are a plurality of spaced rods or arms 42 which incline upwardly and outwardly and clamped on the upper end of each of the arms ii are brackets 43 respectively. The brackets 43 are integral with and extend inwardly from the lower edge of an annulus or ring ll of glass or other suitable translucent or transparent material. The ring 44 is vertically disposed with the walls thereof substantially parallel to the axis of the globe II and is arranged midway between the opposite ends thereof. As shown in Figure 1, the outer surface of the ring 44 is formed with calibrations ll, numbers and other indicia designating the time. It will be apparent that when the lamp I! is lighted, the indicia I will be visible from the outside of the globe, the arrangement being such that the corresponding time in different parts of the world will be indicated. For example, by examining the globe, the time in New York can be readily ascertained and by turmng the globe, the time in Tokio is also readily observed. Ordinarily, the map is divided by lines of longitude into the different time zones to enable the time in different places to be readily observed.

Formed on the inside of the ring ll is an annular series of gear teeth I! with which a pinion ll meshes. The pinion ll is mounted on a vertical shaft 84 having bearing within a box II integral with a plate 48. A suitable clutch 4'! is interposed between the parts of the shaft I to enable the ring 4i and the time indicating ring 44 to be turned or adjusted independently of the 40 upper portion of the shaft ll. Mounted on the upper end of the shaft 44 is a worm wheel 48 with which a worm 4O meshes. The worm 40 is fixed to a horizontal shaft ll forming an extension of the armature of the motor 30. The motor 30 and 48 associated parts are of the ordinary sixty cycle type used for electric clocks and since these motors are well-known to those skilled in this art. further description and illustration thereof is not considered necessary.

50 The plate is is in screw-threaded engagement with the lower end of the tube 2| and is secured to the platform part II and is held in spaced relation thereto by bolts ll which extend through the opening in the ring II. The motor III is secured ill to the plate 40 by a suitable supporting bracket From the above description it will be apparent that the electric motor ll through the connections described imparts turning movement to the so ring Ii, the arms I! turning the glass time indicating ring ll relative to the globe ll so that the indicia thereon will appear through the walls of the globe to be viewed from the outside when the lamp I! is lighted. when it is desired to inspect so different parts of the globe, the same may be turned, and when the globe is turned the motor, time indicating device and associated parts turn with it. In the event it is necessary to make an aa aacos i'ace of the map. The simple construction and arrangement enable the parts to be manufactured and assembled at a relatively low cost.

Numerous changes in details of construction, arrangement and operation may be eifected without departing from the spirit of the invention, especially as defined in the appended claims.
